It doesn't always happen but it did happen in here
You don't need any indexing,you can just create a file list and delete a file from there
Right clicking on it after that don't show you any menus to copy the file but you can still copy it with Ctrl+C or Edit=>Copy

When you try to paste the file,either nothing will happen or explorer will crash(in my case it didn't actually crash,just the explorer window was closed,not the explorer process)
